A Hydraulic Pipe Expanding Collet Chuck is a precision internal clamping workholding device that grips pipes, tubes, bushes, and hollow components from the inside diameter using hydraulic actuation. It provides uniform, distortion-free clamping with high concentricity and repeatability, making it ideal for thin-wall and precision pipe machining in CNC lathes, VMCs, SPMs, and automated production lines.
A Hydraulic Pipe Expanding Collet Chuck is a precision internal clamping (ID clamping) workholding device designed to grip pipes, tubes, bushes, and hollow components from the inside diameter using hydraulic force.
The collet expands uniformly inside the bore, providing distortion-free clamping, high concentricity, and excellent repeatability—especially critical for thin-wall and precision pipe machining.
This chuck is widely used in CNC lathes, VMCs, SPMs, and automation lines where external clamping is not possible or may deform the component.
Applications
Hydraulic Pipe Expanding Collet Chucks are used in:
Key Features
Working Principle
Hydraulic pressure actuates an internal piston or draw mechanism, forcing the expanding collet segments outward.
This creates even radial pressure against the pipe’s inner surface, ensuring secure holding without marking or ovality.
